Flexible membrane separating gas and fluid in hydraulic accumulators to store energy and dampen pressure fluctuations.
A bladder or diaphragm is a flexible elastomeric membrane installed within hydraulic accumulators to physically separate the gas pre-charge (typically nitrogen) from the hydraulic fluid. It expands and contracts in response to system pressure changes, enabling energy storage, shock absorption, and pressure maintenance in hydraulic systems.

Bladder accumulators use a bag-like elastomeric bladder inside a steel shell, while diaphragm accumulators use a fixed elastomeric diaphragm welded to a steel plate. Bladders typically offer higher volume efficiency, while diaphragms are more compact and suitable for lower volumes.
Typical service life is 5-10 years depending on operating conditions. Replace if visible damage, loss of pre-charge pressure, fluid contamination, or reduced system performance occurs. Regular inspection every 6-12 months is recommended.
Common causes include: excessive pressure cycling, temperature extremes, chemical incompatibility with hydraulic fluids, improper pre-charge pressure, contamination, and mechanical damage during installation.
